Lead Software Engineer

Lead Frontend Engineer - Climate Tech - London / Cambridge

Take ownership of front-end engineering at a growing climate-tech company shaping the future of energy planning. You’ll lead the move from a monolithic UI to a modern micro-frontend architecture - while building a high-quality engineering culture from the ground up.

This role is hands-on. You’ll work directly with the CTO, steer architectural decisions, and mentor a growing team. If you enjoy solving complex front-end challenges, scaling modern React systems, and building high-performance data and geospatial visualisations, this is an opportunity to lead with impact.

What you’ll lead

• The migration to a micro-frontend architecture
• The creation of a reusable design system + component library
• High-performance geospatial visualisation (DeckGL, WebGL)
• Front-end standards: TypeScript excellence, testing, CI/CD, performance
• Mentoring front-end engineers + shaping team culture

What you bring

• Expert React + TypeScript (4+ years), 2+ years leading engineers
• Strong architecture background - ideally micro-frontends
• Experience with complex data visualisation or geospatial tools (DeckGL/Mapbox)
• Knowledge of modern bundlers (Vite, Webpack, esbuild)
• Focus on performance, modularity, and scalable front-end systems

Nice to have

• Micro-frontend patterns (Module Federation, single-spa)
• D3/Plotly/Recharts, AWS, testing frameworks

If you want to lead architecture, own engineering quality, and help shape a platform used by half of the UK’s cities, let’s talk.
